Puree all the ingredients in a sturdy blender or food processor. I like it smooth but feel free to leave some fruit bits.
Carefully fill the mixture into your pop molds, leaving a bit of room at the top.
Remove any air bubbles that have formed in the molds. A chopstick or the back of a spoon should do the trick.
Freeze for at least 6 hours (I recommend overnight).
Run the pop mold under hot water for a minute and then gently remove the popsicle.
Notes
If you feel like having some more fun with it, you can divide the yogurt and agave in half and puree them with the two fruits in separate batches. Then alternate between the two mixtures, filling the molds a bit at a time and allowing each layer to set for 30 minutes between additions. You'll have striped pops!
